ARAP2 also known as Centaurin-delta-1 is a protein with ARF-GAP, RHO-GAP, ankyrin repeat, RAS-associating, and pleckstrin homology domains. A phosphatidylinositol-3, 4, 5-trisphosphate-dependent GTPase-activating protein, ARAP2, binds to RhoA-GTP, but lacks the predicted catalytic arginine in the RHO-GAP domain and does not have RHO-GAP activity. It modulates actin cytoskeleton remodeling by regulating ARF and RHO family members. Usually ARAP2 is activated by phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) binding and can be activated by phosphatidylinositol-3,4-bisphosphate (PtdIns(3,4,5)P2) binding, albeit with lower efficiency. ARAP2 associates with focal adhesions and functions downstream of RhoA to regulate focal adhesion dynamics. It is usually detected in brain, thymus, lymph node, thyroid, spinal cord, trachea, heart, skeletal muscle, spleen, kidney, liver, placenta, lung and peripheral blood leukocytes. 

A portion of amino acids 1670-1720 of human ARAP2 was used as the immunogen.

Application Notes
The amino acid sequence used as immunogen is 100% homologous in human (isoforms CRA_a, CRA_b, and CRA_c), 93% homologous in monkey, 87% homologous in chimpanzee and 81% homologous in cow and horse.

ARAP2 Antibody

Western blot analysis of ARAP2 in human kidney lysate in the 1) absence and 2) presence of immunizing peptide using IMG-6381A at 1.0 ug/ml.  IMGENEX’s goat anti-rabbit Ig HRP secondary antibody (IMGENEX, 20301) and PicoTect ECL substrate solution (IMGENEX, 10087K) were used for this test.
